Issue with RTMP input #154

Open arunbpf opened 2 months ago

arunbpf commented 2 months ago

I am trying to use RTMP input with Pipeless. I am able to play the RTMP input stream on VLC and ffplay. But facing error in Pipeless. 

pipeless add stream --input-uri "rtmp://x.x.x.x:1935/live/test" --output-uri "file:///app/rtmp_out.mp4" --frame-path "yolo"

Any idea why this might happen ?

Add GST_DEBUG=4 to try gathering more information about the gstreamer pipeline

I am able process the RTMP source after removing audio from the stream. Now the issue occurs in output RTSP stream. Pipeless is publishing the RTSP stream to the mediamtx server. But I am not able to play it in VLC or ffplay. 

pipeless add stream --input-uri "rtmp://x.x.x.x/myapp/mystream_noaudio" --output-uri "rtsp://localhost:8554/output" --frame-path "yolo"
[2024-08-22T11:33:22Z WARN  pipeless_ai::output::pipeline] Warning in output gst pipeline from element element appsink0.

Why do we see this warning message ?

mmm that should not happen, rtmp and rtsp have been tested to work. It seems to complain about the output gstreamer pipeline for rtsp not having queues. I think it can be fixed by adding a queue compoment here: https://github.com/pipeless-ai/pipeless/blob/a23652b75e380a782ad9e5ee4ab876bde3ec9bde/pipeless/src/output/pipeline.rs#L162
